This topic has been covered in many threads. Some owners have needed to add oil as early as 2kmi, but as their cars have begun to age its been reported that their oil adds have reduced. These cars seem to burn more oil until they truly broken-in which may not be until 20kmi. I'm now at 28kmi and my first & only oil add so far was at 11kmi, but I broke my car in hard. BTW, the oil adds are covered by the warranty.
